Abdeslam was imprisoned after a months-long manhunt following the attacks that left 130 people dead on Nov. 13. Unusually stringent security measures imposed on the 26-year-old include round-the-clock video surveillance from two infrared-enabled cameras located inside his cell.

Berton previously lost an appeal to an administrative tribunal in Versailles to have the devices removed.
